So for some of you that know I was doing my recertification exam for my Physician Assistant license. thankfully done and awaiting my test results. I had a test question about Hyperemesis Gravadium, severe nausea/vomiting in pregnancy, which is believed to be a result of HCG surges and I read a study showed a relationship to Nausea/vomiting and less risk of miscarriage. My miscarriage in May at 9weeks had no nausea/vomiting so I fit the example although when I had my daughter at 19 (if that even counts...lol) I also experienced no nausea/vomiting. So I wondered how correlated it was? Where do you fit in?

My understanding is that it isn't the HCG so much as the progesterone (fondly known as progesterone poisoning) - but I never had any nausea with my miscarriage or my current pregnancy (25 weeks now with one healthy baby) - did you have your 9 week miscarriage fetus chromosomes analyzed? I had a chromosome analysis done on my miscarriage and it was not chromosomally viable, it would never have been a live birth, nothing with those trisomies has ever been born. But I felt the same way at that stage as I did in this pregnancy - my body doesn't seem to react to progesterone (or hcg?) in that way - I get the sore breasts and exhaustion, but luckily, no nausea. Good luck with your test results!

Interesting results ladies, that honestly will help me feel better this cycle if I get a BFP and am not nauseous. Was worried after reading that study that I would be a wreck thinking I'd miscarry again. Who am I kidding I'll probably be a wreck anyway right??

I was very sick for the first 17-18 weeks and had no threat whatsoever of miscarriage. Although miserable with nausea and vomiting for that time, I can honestly say that I was never really scared I was going to miscarry. One nice perk to feeling sick all the time?

This topic is VERY interesting to me right now. With my first pregnancy, I had hyperemesis from right before a positive pregnancy test until a couple of hours after I delivered at 38 weeks.

Right now, I am 7w2d pregnant. It's still about 50/50 as to whether we'll make it (low betas, baby measuring small, etc.) This time I have had morning sickness (mild) since about 5 weeks. At about 6 weeks, it ramped up significantly and in the past 3 days it's been awful. I can't believe I may have to take Zofran for a potentially nonviable pregnancy. So frustrating! Next ultrasound is tomorrow.

I had moderate m/s (nausea, all night every night, but no vomiting thanks to diclectin) and I m/c'd around 8 weeks. Had the m/s from week 5, and it lasted until a few days after I started spotting. Just unlucky, I guess.

Welcomed our wonderful identical twin boys on April 16, 2012 and their sweet baby brother on February 25, 2014.

For me the sickness has lasted for 9 weeks and I have been taking Zofran for the last 5 weeks. I lost ALOT of weight. My last pregnancy was the same, although not as bad (didn't have to take Zofran). I never had a m/c.
As for my mom...her first two pregnancies she didn't have any symptoms, her last pregnancy she was sick before she knew she was preggers until she delivered. So, who knows!?

This is an interesting topic - I was really nervous about not having any nausea with my last pregnancy. I had a lot of dizziness until 12w, but I wasn't really nauseous. I went on to deliver three healthy (albeit small) babies at 31w5d. With my previous three losses, I didn't have any morning sickness either. They were all first trimester losses.

My mother and sister never experienced any morning sickness, and between them delivered four healthy babies at, or close to, term. From what I've read (on Dr. Internet FWIW), presence or absence of morning sickness may be more genetic than indicative of m/c.

I agree that there's most likely a genetic component - my Mom was sick the whole time with my sister and until 20 weeks with me (and then "not great" after 20 weeks but better.) My sister was sick with her pregnancy until about 16 weeks and then still mildly nauseous the rest of the pregnancy.

Just an update for me, I did end up taking Zofran for the last week of this pregnancy which ended with no h/b. I just had a d&c today and am already feeling less nauseous. Very sad, but less nauseous.

I think it really depends on the person and how the HSG affects you. My friend had twins and had ZERO morning sickness. I've had one full term birth, one miscarriage at 11 weeks and another baby that I lost at 17 weeks and had morning sickness with all three. All three of them started around 6-7 weeks and ended around 10-12 weeks.

I think the co-relation is that if you are having morning sickness it is seen as a good sign because it means that the HSG in your body is increasing...... but if you don't have morning sickness it doesn't mean that you are going to miscarry it might mean that your body is not as sensitive to it or it's too early.

I am a perinatal epidemiologist and I have collected several reviews on this well-documented subject. If you PM me your email address, I would be happy to send them to you - they are too big to send on IVF.CA email.

Of note, the difference in survival in NVP vs.non-NVP become more apparent as you age and with vomiting (not just nausea).
